The hinge strap 13, which is shown in Figure 3 and corresponds to the strap 13 of the bottom hinge B shown in Figure 1, has a pair of spaced hinge lugs 20-20 which are substantially the reverse of the lugs 17-17 of the link strap shown in Figure 4.. The lowenlug 20-is also in the form of a hook and is oilset downwardlywith respect to the main body portion of the strap 13. The upper lug 20 of the strap13 is of .U-shaped cross section, as clearly shown'in Figure 3. When the hinge strap 13 and the corresponding link 15 are joined together, the lower lug 1''! of the link 15 is embraced by the lugs 20-26 ofthe cooperating hinge strap 13, the upper lug 20 being entered between the lugs 17-17.

are connected and serves as hinge pin means for ioiningthe hinge sections1'3: and 15 of eachfhi'nge memberfB. As shown; the bar C includes a substantially'. rectangular centralsection 21" having end members 22-22 secured thereto, each end member having: a Iorked portion at the inner end embracing thebar 21 and being riveted thereto. Each: end section 22 is provided with an elongated cylindrical portiori 23 which is journaled inrthe hinge lugs 17-17 and 20-20 of the'link. strap 15 and: hinge strap 13 ofthecorresponding hinge member 13. As will be evident, in addition to servingas'hinge pin means, the end sections 23 also serve as journal members for rotatably supporting the operating'bar'on the door. At the upper and lower ends the bar is provided with crank members 24-24 which are'formed integral with the sections 23-23 and-provide keeper engaging'means' which is effective during'op'ening andclosing of the door;

In applying, thehingie strap 13 and the hinge link 15 to the operating bar; the hinge strap 13 is preferably first'att'achedby disposing the same at an angle to the bar with the journal portion. 23 disposed between the' two hinge lugs'20-20i The hinge member'is then turnedso as to enter the journal portion-of the bar'within the openings of the 'lugs zo-zoby bringing thesame to a: osition at right angles to the axis of the bar; The hingelink strapls is applied in asimila: manner, but'asis evident, must be turned to'a positionat right angles to the strap 13 while being attached to thebar.

. The operating bar.D is mounted on the door'at the side: opposite to thesbarC', adjacent to the vertical. edge of said door; The bar comprises: a central section 25 of substantially rectangular cross section and end members, 26-26 which have cranks 27-27 at the outerends thereof forming keeper engaging means. Inwardlyv of. the crank member 27' each end section 26- isprovided with a cylindricalijournal portion28 rotatably mounted in one of thebrackets F. Eachend sectionQ2 6 is forked, and said forked portion receives the end of the operating bar whichis riveted thereto. The bearingbrackets F-F which supportthe bar D are of similar design, each comprising a platelikej section which is fixed to the door: and a pair of spacedfbearing lugs 29-29". The bearing lugs 29-29 are the" form of hook members which are reversely arranged, each hook member comprising an end section which is disposedsubstantially parallel. to the main bodyportion of the bar with the bearing portion 28 of the bar dis posed between said lugs, the bracket being then turned to the position shown in Figure 1.

The keepers E-E which are arranged in pairs cooperating with the two bars are provided with the-usual guide slots for receiving the ends of the crank members while actuating the door to open or close the-same. The keeper members of each pair are disposed above and below the corresponding operating bar and are fixed to the side wall of the car. Each operating bar C and D is provided with an actuating handle lever of the usual design. As shown, each lever is pivotally connected to the central member of the corre- "responding bar by means of a pin 30. Each lever also cooperates with. the usual latch bracket 31 which'is adapted to receive the ordinary car seal. Inclo'sing'thedoor, the same is swung to partly closed-rv position on the hinge members B, whereby the crank portions of the operating bars C and D are disposed to engage with theslots oi the corresponding keepers upon rotation of said bars. The 'b'ar' C ispreierably first operated by rotating the same the proper direction to enter the members thereof" within the slots ofthe keeperdE-E and. cam' the door into the door opening. The bar D is then operated in asimilar manner to force the corresponding side portion of -the door into the opening. In opening the door,-the operation is substantially the reverse ofthat described, the bar Dbeing first rotated to force the; corresponding side of the dooroutwardly." bar C is thenoperated to force the corresponding side of the door out of the door opening, thereby completely disengaging the door and permitting'the same to be swung to fully opened position on'the hinge members B-B.
